![]() You can even convert them into pretty nice slide shows.Ģ) Embed code in text - After running an analysis, how do you get your results into Word? Type them by hand? Copy-and-paste? Both are a pain and error prone. With R Markdown, we can change between these formats with a single click (or a single line of code). PDF to HTML? Maybe you know how to do that but I don't. These advantages include:ġ) Versatility- Want to convert a Word document into pdf? That's not too hard. ![]() R Markdown has many advantages compared to creating reports in Word or GoogleDocs. By mixing R code with plain text, we can create dynamic reports that replicate the analytical processes, show the code underlying these processes, create the output from our analysis (figures, summary statistics, etc.), and provide all of the necessary text explanations to go along with the code and output. R Markdown gives us all of the formatting options available for Markdown plus the ability to embed, display, and run R code in our documents. In this course, we will use a specific 'flavor' of Markdown called 'R Markdown'. The nice thing about Markdown is that because it uses standard ways to express specific formatting options, you can convert your documents into different output formats very easily. The formatting only shows up when you render the Markdown file to create another type of document (pdf, html, even Word). We'll learn about options like headers, lists, mathematical symbols and equations, and figures later in this tutorial and throughout the semester.Īs you're writing, the text won't look bold or italic or whatever (this is not 'what you see is what you get', it's 'what you see is what you type'). These are just a few of the many formatting options you can include in a Markdown document. Italics is done by putting one *asterisk* around the text. So to make something boldface you have to tell Markdown to do that by putting two **asterisks** on either side of the word or phrase. ![]() The biggest difference between Markdown files and Word documents is that formatting Markdown documents occurs in the document itself rather than behind the scenes. Markdown files are plain text files, meaning that they can be created and edited using text editors (like NotePad on Windows or TextEdit on Mac). docx file using an older version of Word, only to find that it doesn't look the way thought it would? Have you ever inserted a figure only to have it jump to another page or get 'anchored' to the bottom of a page? These are just a few of the problems that occur when your document has a bunch of hidden formatting code that you cannot see or understand. Have you ever had Word act in ways that you don't fully understand? Of course! We all have. But for more advanced users, it can actually be problematic. This makes wysiwyg editors relatively easy to use for beginners. There is code behind the scenes that creates these changes but users don't see the code, only the formatting output. All sorts of other formatting options, including making headers, inserting figures, adding page numbers, etc., are possible by clicking on buttons. This means that when you highlight text and click the boldface icon in Word, the text appears bold on your screen. Word processors are referred to as "what you see is what you get" ( wysiwyg) text editors. Many of you have probably created a report or a paper using a word processor like Microsoft Word or Google Docs. What is Markdown? Let's start with what it's not. Before we discuss what R Markdown is, we need to discuss what Markdown is. The key idea is that when you have a BibTeX database (a plain-text file with the conventional filename extension. Section 2.8 of Xie ( 2016) has explained the details. There are multiple ways to insert citations, and we recommend that you use BibTeX databases, because they work better when the output format is LaTeX/PDF. Footnotes are put inside the square brackets after a caret ^, e.g., ^. The syntax for images is similar: just add an exclamation mark, e.g., !(path/to/image). Hyperlinks are created using the syntax (link), e.g., (). To include \(n\) literal backticks, use at least \(n+1\) backticks outside, e.g., you can use four backticks to preserve three backtick inside: ```` ```code``` ````, which is rendered as ```code```. To mark text as inline code, use a pair of backticks, e.g., `code`. A pair of carets ( ^) produce a superscript (e.g., Cu^2+^ renders Cu 2+). A pair of tildes ( ~) turn text to a subscript (e.g., H~3~PO~4~ renders H 3PO 4). ![]() ![]() Bold text is produced using a pair of double asterisks ( **text**). Inline text will be italic if surrounded by underscores or asterisks, e.g., _text_ or *text*. 19.7 Output arguments for render functions.16.5.4 Create a widget without an R package.2.1.4 2017 Employer Health Benefits Survey. ![]()
